IEC 62271-102:2001

High-voltage switchgear and controlgear - Part 102: Alternating current disconnectors and earthing switches

Applies to alternating current disconnectors and earthing switches, designed for indoor and outdoor enclosed and open terminal installations for voltages above 1 000 V and for service frequencies up to and including 60 Hz. It also applies to the operating devices of these disconnectors and earthing switches and their auxiliary equipment. Additional requirements for disconnectors and earthing switches in enclosed switchgear and controlgear are given in IEC 60298, IEC 60466 and IEC 60517. Note: Disconnectors in which the fuse forms an integral part are not covered by this standard. This first edition cancels and replaces the third edition of IEC 60129 published in 1984, amendment 1 (1992) and amendment 2 (1996) and constitutes a technical revision. In addition, it replaces IEC 61128, IEC 61129 and IEC 61259, which are hereby withdrawn and cancelled. This bilingual version (2003-07) replaces the English version. The contents of the corrigenda of April 2002, May 2003, February 2005 and June 2014 have been included in this copy.

Appareillage à haute tension - Partie 102: Sectionneurs et sectionneurs de terre à courant alternatif

S'applique aux sectionneurs et aux sectionneurs de terre à courant alternatif, prévu pour l'intérieur ou l'extérieur dans des postes sous enveloppe ou de type ouverts, pour des tensions supérieures à 1 000 V et des fréquences de service jusques et y compris 60 Hz. Cette norme s'applique également aux dispositifs de commande de ces sectionneurs et sectionneurs de terre et à leurs équipements auxiliaires. Des règles complémentaires pour les sectionneurs et les sectionneurs de terre intégrés dans l'appareillage sous enveloppe sont données dans la CEI 60298, la CEI 60466 et la CEI 60517. Note: Les sectionneurs dans lesquels un fusible fait partie intégrante, ne sont pas couverts par cette norme. Cette première édition annule et remplace la troisième édition de la CEI 60129 parue en 1984, l'amendement 1 (1992) et l'amendement 2 (1996) et constitue une révision technique. De plus, elle remplace la CEI 61128, la CEI 61129 et la CEI 61259 qui ont été annulées. Un tableau de références est présenté à la fin de cet avant-propos. Cette version bilingue (2003-07) remplace la version monolingue anglaise. Le contenu des corrigenda d'avril 2002, mai 2003, février 2005 et juin 2014 a été pris en considération dans cet exemplaire.

COMMON NUMBERING OF IEC 62271 PUBLICATIONS FALLING UNDER
THE RESPONSIBILITY OF SUBCOMMITTEES SC 17A AND SC 17C
In accordance with the decision taken at the joint SC 17A/SC 17C meeting in Frankfurt, June
1998 (item 20.7 of 17A/535/RM), a common numbering system has been established for the
publications falling under the responsibility of SC 17A and SC 17C. IEC 62271 - High-voltage
switchgear and controlgear is the publication number and main title element for the common
publications.
Numbering of these publications will apply the following principle:
a) Common standards prepared by SC 17A and SC 17C will start with IEC 62271-1;
b) Standards of SC 17A will start with IEC 62271-100;
c) Standards of SC 17C will start with number IEC 62271-200;
d) Publications prepared by SC 17A and SC 17C will start with number IEC 62271-300.
The table below relates the new numbers to the old numbers. The parts numbered (xxx) will
be given a final number pending the decision to publish the revised publication as standard or
technical report.
